i dont know if they allow it, but I hiked Loon a week after it closed last year, i was up at my condo cleaning up, and decided to go check out the park (since my condos on the mountain). There was a rail set up, which just needed a little work on the jump, and nobody around, so me and my brothers just grabbed our skis and had a lil sesh on it.
